Pretty basic question: I have a headphone listening area set up which includes my turntable, phono amp, CD player, and headphone amp (see profile for models). I want to find a high-quality method of quickly switching between listening to my turntable and listening to my CD player, rather than unplugging and replugging cables. Is there a recommended switchbox of some kind that won't affect audio quality - that doesn't cost a bundle? I could get something at RatShack, but am hoping there's an "audiophile approved" piece of equipment that would fit the bill. What does everyone here use?
